Order 8 of the following sentences so that they form a logical
proof by contradiction of the statement:
If the sum of two integers is even then they have the same parity.
• Let x and y be opposite parity integers with even sum.
• x+y is odd
Assume x + y even implies x and y have the same parity.
• x is even and y is odd or x is odd and y is even
x+y=2k+1+2j = 2(k+j)+1
• Hence x and y have the same parity
• Parity is not knowable without a paring knife
• Ek, j€ Z such that x = 2k+1 and y = 2j
• Presume the provided statement is false.
• Without loss of generality, assume x is odd and y is even
• Let x and y be integers with the same parity but with an
odd sum.
